Abstract
Description
Technical Field
[0001] The present invention relates to the field of battery processing technology, and in particular to a high-temperature stabilization method, system, medium and equipment for electrolytes in solid-state batteries. Background Art
[0002] Solid-state batteries are a type of battery technology that uses solid electrolytes instead of liquid or gel electrolytes. Compared to traditional liquid batteries (such as lithium-ion batteries), solid-state batteries have many potential advantages, including greater safety, longer service life, and higher energy density. Therefore, solid-state batteries have attracted widespread attention in areas such as electric vehicles, portable electronic devices, and energy storage systems.
[0003] Solid-state batteries work similarly to traditional lithium-ion batteries, but their electrolytes are different. In solid-state batteries, ions are transported between the positive and negative electrodes through a solid electrolyte rather than a liquid or gel electrolyte.
[0004] The ionic conductivity of the electrolyte is one of the key indicators of solid-state battery performance. Temperature changes have a significant impact on the ionic conductivity of the electrolyte. During the use of solid-state batteries, the ionic conductivity of the electrolyte generally increases with increasing temperature within the low to medium temperature range (usually 25°C to 60°C).
[0005] When the temperature increases, the thermal energy of the ions in the electrolyte increases, making it easier for the ions to overcome the lattice resistance or the ion migration energy barrier of the electrolyte, thereby increasing the migration rate of the ions.
[0006] As the temperature increases, the migration of ions in the electrolyte becomes more active, especially for materials with high ionic conductivity (such as lithium aluminum zirconium oxide LLZO, sulfides, etc.), the effect of temperature on improving ionic conductivity is more significant.
[0007] However, when the temperature rises to a certain level (e.g., above 60°C or higher), the stability of the electrolyte material may be threatened as the temperature rises further. For example, some oxide electrolytes (e.g., LLZO) may undergo phase transition or structural degradation at high temperatures, while sulfide electrolytes (e.g., Li10GeP2S12) easily react with moisture in the air at high temperatures, resulting in a decrease in electrolyte performance.
[0008] Temperature changes may cause thermal expansion or contraction of the electrolyte inside the battery, resulting in changes in the microstructure of the electrolyte material and even cracks or delamination, affecting ionic conductivity.
[0009] Especially when solid-state batteries are used to drive cars, as the car runs for a long time, the electrolyte in the solid-state battery will be discharged for a long time, accompanied by the release of high temperature, which will cause the internal temperature of the solid-state battery to rise sharply. When the heat cannot be discharged, the solid-state battery is very likely to spontaneously combust, resulting in fires and causing personal accidents.
[0010] The existing method of cooling solid-state batteries is to use liquid cooling, but liquid cooling has the following problems: the temperature of the electrolyte near the outside of the solid-state battery drops faster than the temperature in the center, resulting in large temperature differences in the electrolyte of the solid-state battery, making the cooling effect poor.
[0011] Secondly, during the use of solid-state batteries, if the fixed power is maintained for a long time to dissipate heat and cool the electrolyte of the fixed battery, the energy consumption of the fixed battery will increase, thereby reducing the battery life of the fixed battery.

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0080] The present invention provides a high-temperature stabilization method for an electrolyte in a solid-state battery, which is applied to a solid-state battery for an automobile. The method comprises:
[0081] S101, periodically acquiring temperature data of a solid-state battery of a vehicle during operation to generate first temperature data;
[0082] S102, screening out a maximum temperature value from the first temperature data to obtain a maximum electrolyte temperature value;
[0083] S103, calculating the actual maximum temperature value of the electrolyte according to the maximum temperature value of the electrolyte and the compensation temperature threshold;
[0084] S104, comparing the actual maximum temperature value of the electrolyte with a preset temperature value;
[0085] S105. If the actual maximum temperature value of the electrolyte is greater than or equal to the preset temperature value, a first heat dissipation instruction is generated and executed to adjust the heat dissipation power of the radiator around the solid-state battery.
[0086] Please refer to Figure 1-Figure 3 In this embodiment, the system periodically obtains temperature data during the operation of the solid-state battery, and obtains and generates first temperature data.
[0087] The maximum temperature value is screened out from the first temperature data, indicating the hottest part in the battery, to obtain the maximum temperature value of the electrolyte.
[0088] The system calculates the actual maximum temperature of the electrolyte based on the maximum temperature value of the electrolyte and the temperature threshold, and compares it with the preset temperature value.
[0089] If the actual maximum temperature value of the electrolyte exceeds the standard, a first heat dissipation instruction is generated and executed to adjust the radiator power to reduce the temperature.
[0090] Through precise temperature monitoring and dynamic heat dissipation adjustment, battery overheating can be effectively avoided, and risks such as spontaneous combustion and thermal runaway can be reduced. The safety of automotive solid-state battery systems can be significantly improved, and the electrolytes in solid-state batteries can be stable at high temperatures.
[0091] Dynamically adjust cooling power and perform temperature control based on actual needs, rather than maintaining a fixed cooling power for a long time, which helps save energy and improve overall system efficiency.
[0092] It should be noted that the system periodically collects temperature data during the operation of the solid-state battery through sensors or temperature detection devices to generate first temperature data, that is, temperature information at the current moment or within a period.
[0093] Regularly acquiring temperature data can provide real-time temperature information for subsequent temperature control adjustments, helping to promptly detect whether the battery has reached or exceeded the safe operating temperature range.
[0094] The system filters the collected temperature data to identify the maximum temperature value, which represents the hottest point in the solid-state battery's current operating cycle. In high-power applications like automotive, where temperatures can vary across different parts of the battery, this maximum temperature can be used to identify the extreme temperature points inside or outside the battery.
[0095] By selecting the maximum temperature value, the system can accurately determine the hottest part of the battery, avoiding focusing only on the overall average temperature and ignoring local high-temperature areas that may cause thermal runaway.
[0096] Based on the obtained maximum temperature value and the preset compensation temperature threshold (the upper limit of safe operating temperature when designing solid-state batteries), the actual maximum temperature value of the electrolyte is calculated, reflecting the temperature state of the battery during actual operation.
[0097] It enables the system to more accurately judge the operating temperature of the electrolyte, avoid overly conservative or overly radical judgments, and improve the flexibility and accuracy of the temperature control system.
[0098] The calculated actual maximum electrolyte temperature is compared with a preset temperature value. If the battery temperature exceeds the preset temperature value, the system will take appropriate heat dissipation measures to ensure battery safety.
[0099] The preset temperature value is a manually set temperature value, and the preset compensation temperature threshold is a temperature value on a curve corresponding to the current temperature value obtained through the temperature curve of the solid-state battery.
[0100] If the actual maximum temperature of the electrolyte exceeds a preset temperature value, the system will generate a first cooling instruction and initiate cooling measures. These cooling measures may include adjusting the cooling power of the radiator to reduce the temperature of the battery.
[0101] Once it is determined that the temperature of the electrolyte is too high, the system will generate a "first heat dissipation instruction" as needed. The instruction will be transmitted to the radiator control system to adjust the power or switch status of the radiator and start the cooling process to reduce the operating temperature of the battery.
[0102] In at least one embodiment of the present application, the method further includes:
[0103] S106: If the actual maximum temperature value of the electrolyte is less than the preset temperature value, perform the next cycle of detection.
[0104] Please refer to Figure 1-Figure 3In this embodiment, the actual maximum temperature of the electrolyte is compared with a preset temperature value. If the battery temperature is normal (i.e., the actual maximum temperature of the electrolyte is less than the preset temperature value), the system skips any heat dissipation operation and enters the next cycle for temperature monitoring.
[0105] By determining whether to activate the cooling system based on the actual maximum temperature of the electrolyte, excessive energy waste can be avoided. The system will only perform cooling operations when the actual maximum temperature of the electrolyte exceeds the preset temperature value, so that the battery management system does not consume unnecessary energy during normal operation.
[0106] Not performing unnecessary cooling operations can reduce temperature fluctuations inside the battery and avoid thermal stress caused by excessive heat dissipation, which may help extend the battery's service life.
[0107] In at least one embodiment of the present application, the method further includes:
[0108] S201, obtaining the speed of the vehicle and generating a first speed;
[0109] S202, calculating the air flow velocity of the vehicle according to the first velocity to generate a first flow velocity;
[0110] S203, calculating a first theoretical temperature reduction value of the air flow per unit time based on the first flow rate;
[0111] S204 : Generate a second heat dissipation instruction according to the first theoretical temperature drop value and the actual maximum temperature value of the electrolyte, and adjust the heat dissipation power of the radiator according to the second heat dissipation instruction.
[0112] Please refer to Figure 1-Figure 3 In this embodiment, the system first obtains the current speed of the vehicle. This is usually obtained through the vehicle's speed sensor (such as a wheel speedometer, GPS module, etc.), generating a first flow velocity. Since the vehicle speed is variable, this is the average speed within the current cycle.
[0113] Based on the first speed, the air velocity around the car can be calculated. There is a certain relationship between vehicle speed and air velocity. Generally, the faster the vehicle speed, the greater the air velocity and the better the heat dissipation effect.
[0114] Through fluid mechanics principles or empirical models, the system calculates the first flow velocity based on the vehicle speed, that is, the speed at which air flows around the vehicle body when the vehicle is moving.
[0115] Based on the calculated air flow rate (first flow rate), the system further calculates the first theoretical cooling value of the solid-state battery due to air flow. Taking into account factors such as air flow rate, radiator surface area, and ambient temperature, the theoretical value of the air flow rate's effect on battery temperature reduction is given.
[0116] After obtaining the theoretical cooling value, the system generates a second cooling instruction based on the actual maximum temperature of the electrolyte (i.e., the battery's operating temperature). This instruction determines whether to activate the cooling system and how to adjust the cooling power to ensure that the battery temperature remains within a safe range.
[0117] The second cooling command is generated by dynamically adjusting the cooling strategy based on vehicle speed and theoretical cooling capacity. If the theoretical cooling value is sufficient, the system can reduce the cooling power; otherwise, it will increase the cooling power.
[0118] Through intelligent calculations based on real-time vehicle speed, air flow rate and battery temperature, the system can dynamically adjust the heat dissipation power to ensure that the battery receives the most appropriate cooling in different working environments.
[0119] Avoid excessive activation of the radiator when cooling is not necessary, thereby saving energy and extending battery life.
[0120] By precisely controlling the heat dissipation system, the battery is always kept at a safe operating temperature, reducing the risk of battery performance degradation or safety hazards caused by overheating.
[0121] Taking into account factors such as vehicle speed, air flow rate and battery temperature, the system can automatically adapt to different driving conditions to ensure intelligent and adaptable heat dissipation control.
[0122] For example, a vehicle is traveling at 120 km / h (the first speed). Based on the vehicle's shape, aerodynamic characteristics, and speed, the system calculates the air velocity. Assume that according to the fluid dynamics model, at a speed of 120 km / h, the air velocity is 30 m / s.
[0123] Based on an air velocity of 30 m / s, the system calculates the first theoretical cooling value for the battery. Assuming the air velocity and the heat exchange efficiency of the battery surface, the theoretical cooling effect of air flow per unit time is 2°C / minute.
[0124] Currently, the actual maximum temperature of the solid-state battery is 70°C. The system compares this temperature with a preset temperature value, assuming the preset temperature value is 80°C.
[0125] The system combines the first theoretical cooling value (2°C / min) and the actual maximum temperature of the electrolyte (70°C) to generate a second cooling instruction, instructing the cooling system to continue cooling in the following period to ensure that the temperature does not exceed 80°C.
[0126] Due to the high vehicle speed and high air velocity, the system expects the radiator to be able to effectively utilize the air flow to dissipate heat. Therefore, the radiator's cooling power may not need to be very high, but only needs to be appropriately adjusted.
[0127] The system adjusts the operating mode of the radiator according to the second heat dissipation instruction so that the battery temperature fluctuates stably between 70°C and 80°C.
[0128] During the following driving cycle, the system continues to monitor the battery's temperature changes and periodically re-acquires vehicle speed, air flow rate, and battery temperature.
[0129] If the vehicle speed changes (for example, slowing down to 60 km / h), the system will recalculate the air flow rate and adjust the cooling strategy. For example, if the lower speed causes the air flow rate to decrease, the system may need to increase the cooling power of the radiator to compensate for the decrease in air flow rate.
[0130] By calculating vehicle speed and air velocity in real time, the system intelligently determines cooling strategies. When the vehicle is moving at high speeds, the system knows the air velocity is high, so it doesn't need to rely too heavily on the radiator. When the vehicle slows down, the system proactively increases cooling power to prevent battery overheating.
[0131] At higher speeds, the system reduces the need for excessive cooling due to the greater air velocity and significant cooling effect, thus saving energy. At lower speeds, the system activates more cooling power as needed to ensure the battery temperature remains within a safe range.
[0132] By precisely controlling battery temperature, the system effectively prevents battery performance degradation and safety hazards caused by overheating. For example, if high temperatures are not promptly addressed, the battery may experience electrolyte degradation, swelling, or even combustion. This technology effectively manages battery temperature, ensuring vehicle safety during operation.
[0133] In at least one embodiment of the present application, the method further includes:
[0134] S205, obtaining the vehicle exterior temperature to generate an ambient temperature value;
[0135] S206, comparing the ambient temperature value with an ambient temperature threshold;
[0136] S207: If the ambient temperature value is less than the ambient temperature threshold, calculating a second theoretical temperature drop value per unit time based on the first flow rate and the ambient temperature value;
[0137] S208: Adjust the heat dissipation power of the radiator according to the second theoretical temperature reduction value.
[0138] Please refer to Figure 1-Figure 3 In this embodiment, the system uses a sensor to obtain the outside temperature of the vehicle and generates an ambient temperature value. This temperature value is the actual temperature of the current outside environment and is generally used to assess the impact of the external environment on the battery cooling system.
[0139] The car's temperature sensors collect real-time external temperature data and transmit it to the battery management system, which converts it into a usable ambient temperature value as an input parameter for the temperature control system.
[0140] Ambient temperature monitoring is crucial for optimizing battery temperature control systems. Changes in ambient temperature directly impact the cooling effectiveness of air flow and the efficiency of the radiator. For example, in cold weather, while low temperatures may aid heat dissipation, they may also cause the battery temperature to drop too low. In hot weather, the external temperature may increase the load on the radiator, leading to battery overheating. By monitoring ambient temperature, the battery's cooling strategy can be more accurately adjusted.
[0141] The system compares the ambient temperature to a preset threshold. This threshold is a fixed value set based on the battery's design and safety requirements to determine whether the current ambient temperature meets the battery's temperature control requirements.
[0142] The result of the comparison will determine the subsequent heat dissipation strategy: if the outside temperature is low, it may help to cool down; if the ambient temperature is too high, heat dissipation needs to be strengthened.
[0143] The system compares the ambient temperature value with the preset ambient temperature threshold. The preset ambient temperature threshold is manually set when the solid-state battery is designed, such as 25°C or 30°C, which represents the suitable temperature range recognized by the system.
[0144] If the ambient temperature is lower than the ambient temperature threshold, the system will proceed to the next cooling calculation; if the ambient temperature exceeds the ambient temperature threshold, the system may need to take cooling measures for the radiator.
[0145] Comparing ambient temperature thresholds helps determine whether external environmental conditions require adjustments to the cooling strategy. For example, in cold weather (ambient temperature below a set threshold), the external temperature may have a positive impact on battery cooling, and the system can reduce the radiator's workload as needed. At higher temperatures, the system will provide more intensive cooling to prevent battery overheating.
[0146] It should be noted that the outside temperature refers to the ambient temperature outside the vehicle, which is usually obtained by an outside temperature sensor (such as an ambient temperature sensor).
[0147] If the ambient temperature falls below the preset threshold, the system calculates a second theoretical cooling value based on the current ambient temperature and vehicle speed. This value represents the cooling effect of air velocity (i.e., air flow velocity under the influence of vehicle speed) on the battery temperature.
[0148] The second theoretical cooling value predicts the cooling capacity of air flow under current conditions based on vehicle speed, ambient temperature, and the heat exchange efficiency between the radiator and the battery surface.
[0149] Based on the current ambient temperature and the first flow rate (air velocity), the system uses a heat exchange model or fluid dynamics formula to calculate the additional cooling effect that air flow may bring. This calculation result is a cooling prediction for low-temperature ambient conditions.
[0150] By calculating cooling based on the ambient temperature, the second theoretical cooling value provides an optimized cooling strategy for cold environments. If the ambient temperature is low and the air flow is fast, the system will predict the cooling effect of the cold air and automatically adjust the cooling strategy to prevent the battery from cooling too low and ensure normal operation.
[0151] Based on the calculated second theoretical cooling value, the system generates a new cooling instruction to adjust the radiator's cooling power. If the second theoretical cooling value is high, indicating that the low ambient temperature and air flow rate are effectively cooling the battery, the system can reduce the cooling power. If the second theoretical cooling value is low, the system increases the radiator's power to compensate for the cooling effect caused by the insufficient ambient temperature.
[0152] Based on the calculated second theoretical temperature drop value, the system intelligently adjusts the radiator's power output. The radiator may adjust the heat dissipation intensity by increasing or decreasing the coolant flow, fan speed, or other methods to ensure that the battery temperature remains within a safe range.
[0153] Intelligent cooling power regulation dynamically adjusts to environmental changes, preventing excessive heat dissipation when temperatures are low and minimizing the negative impact of low temperatures on battery performance. Through precise control, the system ensures optimal battery performance in low-temperature environments, extending battery life and preventing damage caused by low temperatures.
[0154] For example, imagine you're driving an electric car powered by a solid-state battery. The car is traveling in a cold winter environment, with low outside temperatures (e.g., -5°C). To ensure the solid-state battery operates properly in this low-temperature environment and prevent performance degradation or damage, the vehicle's temperature control system needs to dynamically adjust the radiator's cooling power.
[0155] The vehicle is equipped with ambient temperature sensors that obtain the outside temperature in real time. The outside temperature is -5°C.
[0156] The system generates an ambient temperature value based on the sensor data, which is -5°C.
[0157] The system compares the obtained ambient temperature value (-5°C) with the temperature threshold. Assume that the ambient temperature threshold set by the system is 0°C. That is, when the external temperature is below 0°C, the system will consider the ambient temperature to have a cooling effect on the battery.
[0158] Because the current ambient temperature (-5°C) is lower than the set ambient temperature threshold (0°C), the system determines that the external environment is cold and requires additional measures.
[0159] Next, the system calculates the second theoretical cooling value based on the vehicle speed and outside temperature. Assume the current vehicle speed is 100 km / h (i.e., an air velocity of approximately 27.8 m / s).
[0160] Due to the high speed of the vehicle and the high air velocity, the vehicle can generate strong air flow, which will increase the cooling effect. The system uses an aerodynamic model to calculate that the theoretical cooling value that air flow can bring per unit time is 4°C / minute.
[0161] The calculated second theoretical cooling value is 4°C / minute, meaning the combination of low ambient temperature and air velocity is expected to lower the battery temperature by 4°C per minute.
[0162] Since the ambient temperature is low (-5°C) and the second theoretical cooling value is 4°C / minute, the system realizes that the cooling effect of the air flow rate is very strong, so the system will adjust the radiator power according to this data.
[0163] To prevent the battery temperature from dropping too quickly, which may damage battery performance or cause unstable battery operation, the system will avoid excessive cooling by reducing the heat dissipation power of the radiator.
[0164] For example, suppose the system calculates that without proper cooling control, the battery temperature could drop to an unacceptable level over time. To prevent this, the cooling system reduces the intensity of the radiator, activating it only when needed to ensure the battery temperature remains within an acceptable range (e.g., 20°C to 30°C).
[0165] As driving time progresses, the system continuously monitors vehicle speed and ambient temperature. If vehicle speed changes (e.g., due to a reduction in speed or traffic congestion), the system recalculates air velocity and theoretical cooling values and adjusts radiator power. For example, if vehicle speed drops to 50 km / h, air velocity decreases, the system calculates a new theoretical cooling value, and increases radiator power to compensate for the decrease in cooling efficiency.
[0166] In addition, as the external temperature changes, the system will continuously monitor the temperature outside the vehicle and dynamically adjust the temperature threshold to ensure that the battery temperature is always within a safe range.
[0167] In at least one embodiment of the present application, the method further includes:
[0168] S209: If the ambient temperature value is not less than the ambient temperature threshold, execute the first heat dissipation instruction to adjust the heat dissipation power of the radiator around the solid-state battery.
[0169] Please refer to Figure 1-Figure 3 In this embodiment, the subsequent heat dissipation instruction is triggered only when the external environment temperature is not less than the set ambient temperature threshold. Only when the ambient temperature reaches or exceeds a certain value will the system determine that heat dissipation measures need to be taken to reduce the battery temperature.
[0170] Ensure that the cooling control is activated only when necessary. Avoid unnecessary cooling activation, save energy, and avoid unnecessary cooling when the ambient temperature is low, thereby reducing the energy consumption of the system.
[0171] Avoid unnecessary overcooling of the battery, as the battery's heat dissipation requirements will be relatively large when the ambient temperature is high.
[0172] Once the system detects excessive external temperature and confirms the need for cooling measures, it issues a first cooling command. This command activates the radiator, which then adjusts its cooling power as needed to increase heat dissipation, helping to dissipate heat from the battery and prevent overheating within the battery.
[0173] The radiator can be a liquid cooling system (dissipating heat through liquid circulation) or an air cooling system (increasing airflow through fans, etc.), etc. The specific working method depends on the system design and the heat dissipation requirements of the battery.
[0174] By adjusting the heat sink power, the battery temperature can be kept within a safe operating range, preventing overheating, which could lead to performance degradation, reduced charging efficiency, and even dangerous conditions such as thermal runaway.
[0175] Automatically adjusting the radiator power can adjust the system's heat dissipation according to actual needs, avoiding energy waste caused by excessive heat dissipation. It can use energy more efficiently and optimize battery operating efficiency.
[0176] Through real-time temperature monitoring and precise heat dissipation regulation, the battery's operating temperature can be efficiently managed to avoid performance degradation and safety risks caused by high temperature.
[0177] The system can automatically adjust the power of the radiator according to real-time changes in external ambient temperature, ensuring that the solid-state battery can maintain optimal working condition under different climatic conditions.
[0178] In at least one embodiment of the present application, the step of periodically acquiring temperature data of the solid-state battery of the vehicle during operation, before generating the first temperature data, further includes:
[0179] S301. Obtain the output power of the solid-state battery of the vehicle in this cycle to generate a first output power value;
[0180] S302: Compare the first output power value with a power threshold;
[0181] S303: If the first output power value is greater than the power threshold, perform periodic data acquisition.
[0182] Please refer to Figure 1-Figure 3 In this embodiment, after monitoring the output power of the solid-state battery, the system generates the first output power value within the cycle, that is, records the power data of the battery.
[0183] By regularly obtaining the battery's output power, you can understand the load on the battery under specific operating conditions. When the battery output power is high, it generates more heat, requiring more effective heat dissipation. Conversely, when the output power is low, the battery generates less heat, requiring less heat dissipation.
[0184] By monitoring the output power of solid-state batteries, we can accurately grasp the battery load conditions and provide data support for subsequent temperature management.
[0185] Effectively identify heat dissipation requirements during high-load operation, improve the response speed of the heat dissipation system, and ensure safe battery operation.
[0186] The system determines whether further heat dissipation control measures need to be taken by comparing the first output power value with the power threshold.
[0187] The system obtains the battery's output power (a first output power value) and compares it with a preset power threshold. If the battery's output power is greater than the threshold, it indicates that the battery is under high load, and the system initiates the next step of heat dissipation control.
[0188] By setting power thresholds, the system can intelligently determine whether the battery is under high load. This allows the system to make different cooling decisions based on different operating conditions, thereby improving system energy efficiency and response speed.
[0189] Once the system detects that the battery output power exceeds a preset power threshold, it initiates periodic data acquisition, periodically acquiring battery temperature data under this high power load. This allows real-time tracking of battery temperature and prompt response to overheating risks.
[0190] When the battery is under high load, it generates more heat. Therefore, to prevent overheating, the system needs to obtain battery temperature data more frequently to ensure that the battery temperature remains within a safe range. This ensures that the temperature control system can respond in real time when the battery is under high load, preventing damage from overheating.
[0191] By frequently acquiring temperature data, the system can more accurately grasp the temperature change trend of the battery, thereby making timely and effective heat dissipation adjustments to avoid battery overheating.
[0192] Monitor battery temperature in real time to detect overheating risks in a timely manner and avoid battery damage or safety hazards caused by excessive temperature.
[0193] Through periodic data acquisition, the system can dynamically adjust the cooling strategy according to changes in battery load to achieve more efficient thermal management.
[0194] By monitoring the battery's output power in real time, the system can accurately determine whether the battery is in a high-load working state and reasonably judge whether it is necessary to obtain temperature data more frequently for temperature control.
[0195] Periodic data acquisition ensures that when the battery is under high load, it can respond quickly to temperature changes and adjust the power output of the cooling system in time to avoid battery overheating.
[0196] Avoid battery overheating and ensure that the battery always operates within a safe temperature range, thereby reducing battery loss and extending battery life.
[0197] For example, assume that an electric vehicle is traveling at a speed of 120 km / h. The vehicle's battery management system (BMS) detects that the output power of the solid-state battery is 350W (the battery provides higher power at high speeds) and generates a first output power value of 350.
[0198] The power threshold set by the battery management system is 300W, which means that if the battery output power exceeds 300W, the system will think that the battery is working at high load and will cause overheating.
[0199] Since the current battery output power is 350W, which is greater than the power threshold of 300W, the system recognizes that the battery load is high and starts periodic data acquisition.
[0200] The system starts to periodically obtain battery temperature data. Assume that the system obtains temperature data every 5 minutes.
[0201] Generate the first temperature data: obtain the battery temperature every 5 minutes. Assume that the battery temperature is 65°C, 68°C, 72°C, etc. during each data collection.
[0202] Assume that the system's preset temperature threshold is 75°C. That is, when the battery temperature exceeds 75°C, the system needs to activate the heat dissipation function to prevent the high temperature from affecting battery performance.
[0203] After obtaining the temperature data, the system determines that the battery temperature has not reached the threshold of 75°C at 72°C, so emergency cooling is not required for the time being.
[0204] Since the battery temperature is still below 75°C, the system continues to monitor the battery temperature changes and periodically obtains data. If the battery load increases, the battery temperature may continue to rise.
[0205] Assume the outside ambient temperature is 15°C (a relatively low ambient temperature). Due to the low outside temperature, the system believes that the cooling effect of natural wind may be sufficient to help lower the battery temperature. Therefore, based on the ambient temperature and vehicle speed, the system calculates the air flow rate and then calculates the second theoretical cooling value.
[0206] Assuming that the second theoretical temperature drop value is calculated to be 3°C / minute, it means that even without additional heat dissipation power, the battery temperature can be cooled by 3°C / minute.
[0207] If the battery temperature approaches or exceeds 75°C during subsequent data acquisition, the system will generate a first cooling instruction based on the calculated temperature change trend, instructing the cooling system to increase cooling and keep the battery temperature within a safe range.
[0208] In at least one embodiment of the present application, the method further includes:
[0209] S304, calculating a theoretical heat release value of the electrolyte per unit time according to the first output power value to generate a theoretical heat value;
[0210] S305. Obtain the temperature value of the solid-state battery of the vehicle at the beginning of the current cycle to generate the temperature value of the previous cycle;
[0211] S306, calculating the theoretical calorific value of the current cycle based on the theoretical calorific value and the temperature value of the previous cycle, and generating a theoretical temperature rise value;
[0212] S307: Adjust the heat dissipation power of the radiator according to the theoretical temperature increase value.
[0213] Please refer to Figure 1-Figure 3 In this embodiment, when the battery output power (first output power value) is known, the theoretical heat release value of the electrolyte is calculated using these parameters.
[0214] At the beginning of each time period, the battery management system (BMS) obtains the current temperature value of the battery and monitors the battery status in real time through the temperature sensor.
[0215] This is the battery temperature data from the previous cycle, representing the battery's thermal state during the previous period. This temperature value is used as a reference for comparison with the new temperature data to determine whether the battery has experienced an abnormal temperature rise.
[0216] Based on the temperature value of the previous cycle and the battery's output power (theoretical heat release value) in the current cycle, the heat generated in the current cycle can be estimated. In other words, the theoretical temperature rise value of the current cycle can be calculated based on the relationship between the theoretical heat value and the temperature of the previous cycle.
[0217] Based on the calculated theoretical temperature rise, the system dynamically adjusts the radiator's cooling power. By adjusting cooling power (for example, by adjusting the flow rate of the liquid cooling system or increasing the fan speed), the system effectively controls battery temperature.
[0218] If it is calculated that the battery temperature will rise above the safety threshold, the cooling system will increase its cooling capacity to ensure that the battery temperature does not exceed the standard; if the battery temperature does not rise significantly, the cooling system can reduce the cooling power to avoid energy waste caused by excessive cooling.
[0219] By combining battery output power, temperature and theoretical temperature rise value, the system can achieve more accurate temperature management.
[0220] Avoid battery damage or safety accidents due to overheating, especially under high load or long working conditions.
[0221] For example:
[0222] During acceleration of an electric vehicle, assuming the battery output power is 350W (the power threshold is set to 300W), the vehicle's battery management system (BMS) monitors the battery output power in real time and generates a first output power value. At this point, the first output power value is 350W.
[0223] Assume that the preset power threshold is 300W. In this case, the battery's output power (350W) exceeds the power threshold. Therefore, the battery management system triggers periodic temperature data acquisition and enters temperature monitoring mode.
[0224] Based on an output power of 350W, the system calculates the theoretical heat release per unit time for the electrolyte. Assuming this value is 5W·h, theoretically, this means the battery releases 5 watt-hours of heat per hour.
[0225] At the beginning of the cycle, the battery temperature is monitored by the sensor. Assuming the current temperature is 30°C, this temperature value is the temperature value of the previous cycle.
[0226] The system calculates the theoretical temperature rise for this cycle based on the calculated theoretical heat output (5W·h) and the temperature of the previous cycle (30°C). Assuming the battery's heat dissipation efficiency and heat capacity are fixed, the battery temperature is expected to rise by 1°C, resulting in a theoretical temperature rise of 1°C.
[0227] Since the theoretical temperature increase is 1°C, the battery management system determines that the current temperature increase is within a safe range (assuming the temperature threshold is 45°C), so forced cooling may not be necessary. However, the system may still choose to fine-tune the heat dissipation power of the radiator to enhance heat dissipation to maintain a more stable operating temperature and prevent further temperature increases.
[0228] Assume that after a period of continuous operation, the actual maximum battery temperature approaches 40°C, but still does not exceed the preset temperature threshold of 45°C. Therefore, the BMS system does not immediately initiate forced cooling, but only adjusts the radiator power appropriately based on the temperature rise trend to maintain a stable temperature.
[0229] Assuming the outside temperature is 15°C and the vehicle is traveling at 80 km / h, the system calculates an air velocity of approximately 25 m / s. It then calculates the second theoretical cooling value that can occur per unit time and adjusts the radiator power accordingly to further control the battery temperature.
[0230] Assuming the ambient temperature is 30°C, when the system detects that the external temperature is high, it will automatically execute the first cooling instruction, start or enhance the cooling capacity of the radiator to ensure that the battery temperature does not exceed the safety threshold.
[0231] The battery management system (BMS) monitors the battery's output power, temperature, and external environmental conditions in real time, dynamically calculates the changing trend of the battery temperature, and intelligently adjusts the radiator power based on the predicted results of temperature increase.
[0232] When the battery temperature is too high, the system can automatically adjust the heat dissipation intensity to prevent overheating and ensure that the battery operates within a safe temperature range, thereby improving battery safety, extending battery life, and optimizing battery energy efficiency.
